CEMENTING-MACHINE.

Specification of Letters Patent.

Patented Nov. 5, 1912.

To all whom it may concern.'

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Lynn. in the county of Essex and Commonwealth of Massachusetts, vhave invented certain Improvements in Cementing-Ma'chines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts iii the several figures.

This invention relates to machines for applying liquid material, suoli as cement, to shoes or other stock and'particularly to machines for applying cement to the channeled portions of the soles of shoes.

An object of the invention is toprovide a novel cement applying machine in Which the delivery vof cement Will be controlled by the position of the Work to be coated, the flow of cement being automatically stopped When the Work is Withdrawn from position to re` ceive it, and preferably also being automatically started ivlien the shoe is presented in position to be coated. Y y

A very important feature of this invenf tion consists in a machine arranged to pro# vide a continuous flovv of cement While the Work is in place with means forA automatically sliuttiiig off the delivery of cement when the Work is Withdrawn from receiving position. Preferably, also, meanss provided for starting the lovv Vof the cement when the vvork is moved toward or into its receiving-position, and insuring the continued liovv until the Work is Withdrawn. By stopping the delivery of cement automatically when the slioe is Withdrawn, Waste of cement is avoided and also objectionable overloading of the cement-applying brush which is likely to occur when .the operator controls a valve by a foot treadle and often fails to shut it off as soon as a shoe is finished. By also starting the cement automatically the use of the usual treadle can be entirely avoided and economy in the use of cement effected becausecement will only be delivered While the shoe is in position to receive it. This broad feature of the invention is capable of being embodied in many dilferent constructions and herein are shown `covering the sole fastenings, the discharge member is constructed and arranged to extend to the Working surface of the brush and engage the sole in the angle at the base of the lip and form a guide for positioning the Work both vertically and laterally. There may be employed in combination with this guide a channel lip lifting device arranged to extend under the edge of the overturned lip and raise the edge from t-lie sole so that the full Width of the lip may be coated Without liabilityof spreading cement upon the face of the sole. The channel lip liftingfde-A vice does not need to be long enoughto touch the face of the sole and it may be vi` bratetl to facilitate the raising of the lip and also the feeding of the shoe, particu-l larly aro-und the toe Where the lip is usually crinkled Aor puckered.

Theseand other features of the invention, including' numerous details of construction y and combinations of partswill be more fully explained in connection` With `the drawings and will then be pointed out in the claims.

Figure lis an endelevation, partly in section, of a preferred construction. Fig. 2 is a section through the brush and Work `guiding' foot, a lip-lifting Vdevice being ,shown in the position which it occupies 'when used with thisV construction; Fig. 3

is a section showing the-fastening for the brush;".;Fig. t is a detail of the` cement sliutoff;..Fig. 5 shows a modified arrangement of the shoe guiding foot together with 3 a lip-lifting device and means for vibrating said device; Fig. 6 is a section of Fig. 5;` Fig. 7 shows a further arrangement of the shoe guiding foot especially adapted for Welt vvork; Fig. 8 is a section of Fig. 7 Fig. 9 shovvs a modification.

InFigs. l and 2 a construction is shown in Which a driven brush may beleinployed and in which delivery of cement is coiitrolled by a'Work guide 4:0 provided With blades 42, as shown in Fig. 2, that extend circumferentially with relation to the brush and between or among the bristles. The blades are preferably arranged with relation to the brush for the front blade or the one shown at the left in Fig. 2 to engage the base of the channel Hap and form a guide for determining the lateral position of the shoe with relation to the brush. The work guiding faces of the blades 42 are not concentric with relation to the brush and therefore permit the work to be positioned more or less closely to the brush by resting it at different points on the blades or by rocking it about the ends of the blades which terminate approximately under the axis of t-he brush. The guide 40 is fast to a rocker or shaft 44, which also carries an arm 45 that has a cement passageway communicating with the main portion of the conductor 10, which in turn leads from a suitable reservoir 6. The outer end of the arm 45 is provided wit-h a depending tube 46, the lower end of which is adapted to fit and rest upon a trough 48, shown in Fig. 4, that is supported in fixed position with relation to the frame of the machine. A screw 50 is adjustable in the tube 46 to vary the size of the opening from the arm passage into the tube and control the flow of cement when the tube is raised from the trough. The rock-shaft 44 carries a plate 52 in which is mounted a spring 54 acting against a stud 55 that extends through a slot in the plate and into the conductor 10. The parts just described are so arranged that the lower end of the tube 46 normally rests by the weight of the parts and the pressure of the spring 54 against the upper face of the trough 48, thus stopping the flow of cement into the trough and from thence to the brush. l/Vhen the parts are in this position the blades 42 are located below the periphery of the brush, as indicated in dotted lines in Fig. 2. Vhen the work is presented to the machine the blades are lifted into the full line position in Fig. 2 and through the rockshaft 44 the tube 46 is lifted into the position shown in Fig. 1 to permit the flow of cement into the trough and from thence to the brush. As soon as the work is withdrawn from the brush the tube and the plates will be reversely moved to shut off the cement automatically. A cement box 56 may be supported in the relation to the brush illustrated in Fig. 1 and provided with a gate 58 that can be set by the screw 59 in position to regulate the quantity of cement carried by the brush.

The brush may be connected to a forward extension of the shaft 4 by the locking connection shown in Fig. 3 which comprises a bolt 60 having a cam slot 62 adapted to receive the inner end of a screw 64. The enlarged head of the bolt 60 is provided with openings to receive a spanner wrench by means of which it may be turned to clamp the brush againstl the end of the shaft. The slot 62 is inclined in the direction to cause the brush to be more firmly locked by the resistance offered by the work to the rotation of the brush.

In Fig. 5 the guide arm 40 is shown as replaced by an arm 65 that extends over the front side of the brush and is provided with a work guide 66 adapted to extend under the channel Hap, as shown in Fig. 6. In order that the guide or lip-lifting device G6 may be vibrated, an extension S1 provided with arms 82 is screwed on the end of the brush shaft, and a member 83 is adjustably fastened to the arm 65 by the screw which holds the lip-lifting device 66 in place, said member being adjusted so as to be engaged by the arms 82 when cement is liowing to the brush.

Fig. 7 shows the guide arm 40 of Fig. 1 replaced by an arm 67 which adjustably supports a guide or foot GS arranged at the rear side of the brush and adapted to extend across in engagement with the feather of the sole and bear against the base of the channel flap as indicated at Fig. 8.

Fig. 9 shows a device 112 for lifting the edge portion of the channel lip and supporting it for the brush to coat the lip with cement without liability of smearing the face of the sole. The lip lifting device preferably is so formed and proportioned with relation to the shoe positioning and guiding means that it does not touch the face of the sole. In this respect this device is' distinguished from that shown in my prior application, Serial No. 211,215, filed June 4, 1904. An advantage for this present construction is that the lifting device will not soil or mar the sole.

In Fig. 9 the lip lifting device is indicated as having vibratory movement which reduces the liability of its catching upon the crumpled portions of the lip at the toe of the shoe. In this ligure I have also shown a different form of work guide and a modified construction of supplying means by which the cement is delivered directly upon the work. The brush serves as a spreader for this cement and it may also take up some cement from the delivery device. This device comprises the conductor section in the form of a trough covered by the spring plate 84. This plate has a foot S5 to be engaged by the feather and the base of the lip of the shoe. The foot thus forms a work guide and also a direct connection by which the plate S4 may be lifted, moved to open the conductor and control the discharge of the cement. The foot 85 may be shaped as shown to form a well within its wallsto retain a small quantity of cement and spread it as the shoe is moved under the ribs 86 of the foot. The outer wall 87 forms a guard to prevent the cement iiowing over the edge of the sole.

Having explained the-nature of this invention, and described a mechanism embodying the same in the preferred form, I claim as new and desire to secure by Letters Patent of the United States 1.
